Fan with a function of far infrared ray emission

ABSTRACT

A fan with a function of far infrared ray emission has a shell, a circuit board mounted in the shell, a stator, a rotator, at least one far infrared radiator. The far infrared radiators will emit far infrared ray, which is further spread with the airflow caused by the rotation of the rotator.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a fan, and particularly relates to afan with a function of far infrared ray emission.

2. Description of the Related Art

The conventional fan has a shell. A circuit board, a stator, and arotator are mounted in the shell. The stator with windings iselectrically connected with the circuit board, the rotator has apermanent magnet mounted therein, and the rotator is rotatably mountedaround the stator. When the fan is actuated electrically, with theelectromagnetism principle, the rotator is driven to rotate and toproduce airflow.

However, the conventional fan can only provide airflow to eliminateheating without any other auxiliary function and is not versatile inuse.

Therefore, the invention provides a fan with a function of far infraredray emission to mitigate or obviate the aforementioned problems.

SUMMARY OF THE INVENTION

The main objective of the present invention is to provide a fan with afunction of far infrared ray emission comprising a shell, a circuitboard, a stator, a rotator, and at least one far infrared radiator.

The shell has a chamber, at least one air inlet and at least one airoutlet. The air inlet and outlet are defined in the shell andcommunicate with the chamber. The circuit board and the stator aremounted in the chamber, and the stator is electrically connected witthhe circuit board. The rotator is rotatably mounted around the statorand has a permanent magnet mounted in the rotator and mounted around andseparate from the stator. The far infrared radiator is mounted in theshell at the outlet and is electrically connected with the circuit boardto radiate far infrared ray, which will be spread with the airflowcaused by the rotation of the rotator.

Other objectives, advantages and novel features of the invention willbecome more apparent from the following detailed description when takenin conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

With reference to FIGS. 1-4, a fan with a function of far infraredemission in accordance with the present invention has a shell (10), acircuit board (20), a stator (30), a rotator (40), and at least one farinfrared radiator (50).

The shell (10) includes a base (11) and a cover (12) mounted on the base(11) with bolt or other fasteners. The base (11) has a chamber, a seat,at least one air inlet (13) and at least one air outlet (14). The seatis formed at the bottom of the chamber, and the air inlet (13) and airoutlet (14) are defined in the shell and communicates with the chamber.In optional embodiments, an air inlet (13) and an air outlet (14) aredefined respectively in the top and the bottom of the shell (10), or twoair inlets (13) are defined respectively in the top and the bottom ofthe shell (10) and at least one air outlet (14) is defined in the base(11) near the bottom of the base (11).

The circuit board (20) is mounted in the chamber above the seat, withcircuitry, inductor, and other electric elements.

The stator (30) with windings is mounted in the chamber above thecircuit board (20), the windings are electrically connected with thecircuit board (20).

The rotator (40) is mounted in the chamber around the stator (30), has ahollow impeller, multiple blades, a permanent magnet (41) and a pintle.The hollow impeller has a cavity in which the stator (30) is mounted.The blades are formed round the hollow impeller. The permanent magnet(41) is mounted in the inner wall of the hollow impeller around andseparated from the stator (30). The pintle is mounted in the center ofthe cavity, mounted in the center of the stator (30) with a bearing, sothat the rotator (40) is able to rotate around the stator (30).

Multiple far infrared radiators (50) are mounted at the air outlets(14), a ventilation space (15) is between each pair of adjacentradiators (50). Each far infrared radiator (50) includes a ceramic chip(51) that is able to radiate far infrared ray, and a heater (52) ismounted in the ceramic chip (51) and is electrically connected with thecircuit board (20) to generate heat and activate the ceramic chips (51)to emit the far infrared ray.

When the fan is actuated to make the rotator (40) rotation, air will bedrawn into the chamber from the inlet (13) and discharged from theoutlet (14) to provide a heat dissipating effect. At this time, theheaters (52) are actuated to generate heat and activate the ceramic chip(51) to emit the far infrared ray, so that the fan in accordance withthe present invention has auxiliary function of far infrared rayemission and is versatile in use.

It is to be understood, however, that even though numerouscharacteristics and advantages of the present invention have been setforth in the foregoing description, together with details of thestructure and function of the invention, the disclosure is illustrativeonly. Changes may be made in the details, especially in matters ofshape, size, and arrangement of parts within the principles of theinvention to the full extent indicated by the broad general meaning ofthe terms in which the appended claims are expressed.
